Farm and management characteristics associated with boar taint

Area of Science:

• Animal Science
• Agricultural Management
• Food Science

Background:

• Boar taint, an undesirable odor in pork, affects consumer acceptance and market value.
• Prevalence of boar taint varies significantly among pig farms in the Netherlands.
• Sensory evaluation by humans is the current standard for assessing boar taint at slaughter.

Purpose of the Study:

• To identify farm and management characteristics associated with varying levels of farm-level boar taint prevalence.
• To provide data for developing targeted intervention strategies to reduce boar taint in pork production.
• To explore potential factors influencing the occurrence of boar taint in boars.

Main Methods:

• A questionnaire was distributed to 152 Dutch pig producers, achieving a 59% response rate.
• Farm-level boar taint prevalence data (from sensory evaluation) were correlated with reported farm and management characteristics.
• Statistical analysis was used to identify significant associations between management practices and taint levels.

Main Results:

• Lower boar taint prevalence was linked to smaller group sizes and increased pen surface area per boar.
• Farms with newer housing equipment, longer fasting periods before slaughter, and higher stocking weights showed reduced taint.
• Using fewer boars from purebred dam lines or specific Pietrain terminal boars was associated with lower taint levels.
• Not restricting feed in the final period before delivery was also correlated with lower taint prevalence.

Conclusions:

• Several manageable farm-level characteristics are associated with reduced boar taint prevalence.
• These findings can inform the development of practical strategies for pig producers to control boar taint.
• Further research is recommended to establish definitive causal relationships between identified factors and boar taint.
